Animated DTS profiles Speulderbos

I animated the vertical DTS profiles we measured at the Speulderbos forest site, and uploaded them to YouTube:

These videos are also archived on Zenodo, and are citable! 

Vertical temperature profiles of the air temperature (red) and the wet-bulb temperature (blue) are animated through time. The measurement tower and an example tree is shown on the right. The time shown is in UTC+1

Different radiation shielding above canopy was available (or absent), which is shown on the right hand side of the video. From 2017/08/03 onwards, a coiled fiber measures the temperature profile in the bottom 1.0 meters.

The measurement method is described in

Part of the raw data (2016) is available on

‘Plug & play’ DTS based sensor concept

To facilitate easier to use DTS measurements, and to make it more standardised ‘plug & play’ DTS sensors could be developed. By using standard fibre optic connectors, these sensors can then be deployed more easily, and the measurements are more reproducable.

As an example, I sketched this soil temperature profiler, based on Campbell Sci.’s SOILVUE10 sensor (image links to PDF file):
